From its launch in 1956, the Day-Date was immediately recognized as the watch worn by influential people. The Day-Date was the first calendar wristwatch to display the day, as well as the date, in its entirety. Faithful to its noble origins, the Day-Date is made exclusively of gold or platinum, the most precious metals.
